Graph generated using tree data of 100 samples in 3 classes. Each node represents a cluster of branches which co-aggregate in geometric space. The size of nodes are proportional to the number of branches, and the color represents the class proportion where darker blue color indicates a stronger proportion of one class and progressively more red indicates less pure nodes. The axis are in arbitrary units and the graph is not anchored
